Directions
In general, you should mix 20 mL of Mineral Blend A and 20 mL of Mineral Blend B with each gallon of water you add to your Tower Garden reservoir. But there are a couple of exceptions:
• For a Tower Garden full of small seedlings, use half-strength nutrients (i.e., 10 mL of A and 10 mL of B per gallon of water). After about three weeks, you can increase the solution to full-strength.
• During hot months—when the water evaporates from the reservoir more quickly—use half-strength nutrients (or add full-strength every other time you fill the reservoir).

Due to its classification as afertilizer, Tower Garden Mineral Blend requires special shipping and handling, which costs $20. You’re probably thinking, “that’s half the cost of the product itself!” And we’re totally with you.

But the Mineral Blend is essential to the success of your Tower Garden. And one order should last for about six months of continuous growing for a single Tower Garden. So if you’re growing year-round, you’ll only need to order Mineral Blend twice a year.
